Investigating - Beginning around 15:10 UTC on May 27th, 2020, we began performing emergency maintenance on our infrastructure in Mumbai, India. No impact to Dyn Managed DNS Nameservers or peripheral infrastructure is expected, although some users may experience additional DNS query latency as traffic is routed to other paths.

Customers with any questions are encouraged to reach out to our Product Support Team.

Oracle strives to provide best-in-class products and services to meet and exceed our customers’ needs throughout all stages of a product’s lifecycle. Because of the resources required to build and support emerging products and solutions, we occasionally need to retire older products and discontinue their support.

On May 31, 2020, our Oracle Dyn China Nameserver Infrastructure will be retired. Any customer still utilizing our China Nameservers after this date will experience DNS resolution failures as a result of this change. Customers should complete DNS migration away from the China Nameservers before May 31, 2020 to avoid downtime.

No impact is expected to any other Oracle Dyn product, including Managed DNS Nameservers, as a result of this change.

Please ensure that all appropriate contacts in your company are made aware of this notice. If you are using our China Nameserver service and have not been in communication with our internal teams, please reach out to our Product Support Team for assistance.

Dear Customer,

Oracle strives to provide best-in-class products and services to meet and exceed our customers’ needs throughout all stages of a product’s lifecycle. Because of the resources required to build and support emerging products and solutions, we occasionally need to retire older products and discontinue their support.

This notice is to inform your company that the Oracle Network L3/L4 DDoS Mitigation Service has been assigned to End of Life (EOL) status and will be retired on May 31, 2020. You will be able to continue to use your service until this EOL date at which time the service will be turned off. At that time, your GRE tunnels and direct connects will be decommissioned. Always On customers must have a migration plan in place prior to May 31, 2020 to avoid network outages.

Please ensure that all appropriate contacts in your company are made aware of this notice.

Resolved -
On May 27th, 2020, starting around 21:27 UTC, we began investigating an issue with the Dyn Managed DNS Portal. Our engineers performed server restarts which mitigated the impact on May 27th, 2020 at 21:57 UTC.

Customers may have been unable to access the Portal to make changes to their DNS Zones and received a "503" error. Access through the API was not affected by this event.

Customers with any questions are encouraged to reach out to our Product Support Team.
